Module sends error type="cancel" <service-unavailable> after receiving content jingle from Xmpp server.

[sowmya-subramaniam8]

Hi,
We are trying to connect to our prosody server to fetch audio content for recording, after sending the presence we receive a jingle containing the xml for the audio content. The module then sends the following immediately after:

<iq type="error" xmlns="jabber:client">
    <jingle xmlns="urn:xmpp:jingle:1">
         <content name="audio"> 
             //rest of the jingle data
          </content>
     </jingle>
      <error type="cancel"><service-unavailable xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/></error>
</iq>

Once this is sent, we get disconnected from the server in 2 minutes. Why is this sent? How can we keep our connection to the server alive?

Please share complete logs with https://github.com/xmppjs/xmpp.js/tree/master/packages/debug (feel free to redact sensitive or verbose data).

It doesn't look like it's related to xmpp.js though...

Hi, these are the logs we get when we run the xmpp code, after going online, we send our presence and receive the relevant data from our xmpp server (prosody)

status disconnect [object Object]
xmpp status---	  disconnect

As you can see the last OUT : is not our code, it happens as soon as we receive audio/video related data from our server, after this is sent we do not hear anything from our server and we are disconnected a few minutes later.

Please help us debug this, we have no idea why the error is even sent out to our server.

Thank you in Advance!

[sonnyp]

The last OUT is a response error from xmpp.js because it receives (the last IN) an XMPP iq that isn't implemented

Similar to how an HTTP server would reply with 404 if the client would make a request to an endpoint that doesn't exist.

You need to add a iq handler

For example

xmpp.iqCallee.set('urn:xmpp:jingle:1', 'jingle', (ctx) => {
  console.log(ctx);
  return true; // replies with an empty iq result
  // or reply with a non empty iq result
  // return xml('jingle', {xmlns: '...'}, ...)
})

See https://github.com/xmppjs/xmpp.js/tree/master/packages/iq#callee

Not sure why you get disconnected though, doesn't seem related - probably related to your server configuration.
